Peer Assist Live Streaming Overlay for Next-Generation-Networks

The rapid evolution of the telecommunication domain increases the performance of different access networks continuously. New services, especially in the domain multimedia content distribution, require higher and higher bandwidth at the user's and service provider's side. Multimedia services like Video on Demand, IPTV, and live streaming were introduced in the past and are still improved in quality and quantity. Multimedia streams and Peer to Peer P2P file sharing dominates the worldwide Internet traffic nowadays and will continue further Schulze, 2009. The user acceptance of enjoying multimedia content over the Internet will grow steadily together with the increasing quality of the available multimedia content. Network operators and service providers have to face the growths by increasing their service platform with higher performance and bandwidth or introducing a scalable solution. In this paper, the authors present an algorithm for scalable P2P live streaming in Next-Generation-Networks NGN that addresses this challenge. An evaluation proves the performance of the implementation of this algorithm in a demo scenario.
